The current workspace is a chocolate tempering system. The current state of the codebase is very bad. The one wrote the code is a very stupid person. I want you to rewrite the whole system based on the documentation provided.
|
||||
|
||||
The code should be clean, well-structured, and follow best practices and utilze design patterns and modular architecture. The system is built using c# and communicates with hardware via Modbus RTU over serial communication.
|
||||
|
||||
Implement the system in Python using FastAPI for the web service, asyncio for asynchronous operations, and SQLAlchemy for database interactions. The system should be modular, with clear separation of concerns between the user interface, control logic, communication, and hardware layers.
|
||||
see docs for specification
|
||||
|
||||
the current code can not be seen as correct reference, but it can be used as a reference for the current state of the system. (which is very bad)

||||
|
||||
#### **Additional Industrial Libraries**

sudo systemctl start tempering-machine
|
||||
```
|
||||
|
||||
## Core Features
|
||||
|
||||
### Chocolate Tempering Process
|
||||
|
||||
The system manages a three-phase chocolate tempering process:
|
||||
|
||||
1. **Heating Phase**: Heat chocolate to target temperature (40-60°C)
|
||||
2. **Cooling Phase**: Cool to tempering temperature (20-40°C)
|
||||
3. **Pouring Phase**: Maintain pouring temperature with precise control
|
||||
|
||||
### Hardware Control
|
||||
|
||||
- **Temperature Monitoring**: 4-zone temperature sensors with ±0.1°C accuracy
|
||||
- **Motor Control**: Mixer, fountain, vibration, and heating elements
|
||||
- **Safety Systems**: Emergency stop, overcurrent protection, temperature limits
|
||||
- **Communication**: Modbus RTU over RS-485 with automatic retry
|
||||
|
||||
### Safety & Monitoring
|
||||
|
||||
- **Real-time Error Detection**: Grid power, temperature, current monitoring
|
||||
- **Automatic Recovery**: Self-healing from communication failures
|
||||
- **Audit Logging**: Complete operational history and change tracking
|
||||
- **Prometheus Metrics**: Performance monitoring and alerting
|
||||
|
||||
## Configuration
|
||||
|
||||
The system uses environment variables and configuration files:
|
||||
|
||||
```bash
|

## Development Guidelines
|
||||
|
||||
### Code Quality
|
||||
- **Type Hints**: All functions must have complete type annotations
|
||||
- **Async/Await**: Use async patterns for I/O operations
|
||||
- **Error Handling**: Comprehensive exception handling with proper logging
|
||||
- **Testing**: Minimum 80% code coverage required
|
||||
|
||||
### Safety Standards
|
||||
- **No Blocking Operations**: All I/O must be asynchronous
|
||||
- **Graceful Degradation**: System continues operating during partial failures
|
||||
- **State Validation**: All state transitions must be validated
|
||||
- **Hardware Simulation**: All code testable without physical hardware
|
||||
|
||||
### Performance Requirements
|
||||
- **Response Time**: < 100ms for safety-critical operations
|
||||
- **Temperature Accuracy**: ±0.1°C measurement precision
|
||||
- **Communication Latency**: < 500ms for Modbus operations
|
||||
- **Uptime Target**: 99.9% availability
|
||||
|
||||
## Monitoring & Maintenance
|
||||
|
||||
### Log Files
|
||||
- **Application Logs**: `/var/log/tempering-machine/app.log`
|
||||
- **Access Logs**: `/var/log/tempering-machine/access.log`
|
||||
- **Error Logs**: `/var/log/tempering-machine/error.log`
|
||||
|
||||
### Metrics
|
||||
- **Process Metrics**: Temperature accuracy, cycle times, error rates
|
||||
- **Hardware Metrics**: Communication latency, sensor readings, motor status
|
||||
- **System Metrics**: CPU usage, memory consumption, disk I/O
|
||||
|
||||
### Backup Strategy
|
||||
- **Configuration**: Automated daily backup of recipes and settings
|
||||
- **Data**: Continuous replication of operational data
|
||||
- **System**: Full system image backup weekly
|
||||
|
||||
## Migration from Legacy System
|
||||
|
||||
The Python implementation maintains compatibility with existing:
|
||||
- **Recipe Formats**: Existing recipes can be imported
|
||||
- **Hardware Configuration**: Same Modbus addressing scheme
|
||||
- **Process Parameters**: Identical tempering algorithms
|
||||
- **Safety Logic**: Enhanced safety with backward compatibility
|
||||
|
||||
## Support & Documentation
|
||||
|
||||
- **API Documentation**: Available at `/docs` endpoint when running
|
||||
- **Technical Documentation**: See `docs/` directory
|
||||
- **Issue Tracking**: GitHub Issues
|
||||
- **Support Email**: support@tempering-machine.com
